Description
This section describes the PACS 300 control and monitoring system. The purpose of
the control system is to issue orders and send them to the executive components of the
washer-disinfector so that a number of process steps can be performed in accordance
with a predetermined template. The order signals are worked out by the computer pro-
gram of the control unit in conjunction with measurements of actual parameter values
for the current program. These are usually times, temperatures and pressures.

The operator communicates with the control unit via a control panel or an ordinary PC.
All operator panels can be used to monitor the processes, since they display all the set

given process, such as batch number, operator number, date, etc., can be entered by the
operator.

The computer contains programs for automatic calibration of the temperature and pres-
sure sensors. Where alternative correction constants are known, they can be entered
manually. The testing functions include means of activating analog and digital outputs
and for monitoring analog and digital inputs.
